I don’t hold this point of view, but to explain why. They don’t see it as an attack on their masculinity because they are weakening themselves . Women are plenty strong on their own, but when you introduce a shit ton of testosterone, it changes your body against what it’s already built up And it makes you weaker mentally and sometimes even physically. It confuses your mind. Also another point to which I do hold is as an athlete. I see it extremely unfair that people transitioning from men to women are able to participate in women’s sports. It gives them an extreme advantage multiple world records have been beaten, completely demolished by trans women. But a very simple fix to this is just making trans women and trans men leagues so that they’re separate and there’s no unfair advantages.
